functioning of statin is based on competitive inhibition

[74], Atorvastatin is relatively inexpensive. [66] In atorvastatin's case, a key element of the overall synthesis was ensuring stereochemical purity in the final drug substance, and hence establishing the first stereocenter became a key aspect of the overall design. Figure below explains the functioning, substrate comes and binds to enzyme undergoes product formation and releases the site, making it available for new substrate to come and bind. [58], A few cases of myopathy have been reported when atorvastatin is given with colchicine.[15]. Hypercholesterolemia is considered to be one of the major risk factors for atherosclerosis which often leads to cardiovascular, cerebrovascular and peripheral vascular diseases. Therefore, statins protect K Ca 2.3 channel function by inhibiting isoprenylation. [35] Often, bosentan, fosphenytoin, and phenytoin, which are CYP3A4 inducers, can decrease the plasma concentrations of atorvastatin.

"[54] Small studies (using mostly young participants) examining the effects of grapefruit juice consumption on mainly lower doses of atorvastatin have shown that grapefruit juice increases blood levels of atorvastatin, which could increase the risk of adverse effects. The symptoms were not serious, and they were rare and reversible on cessation of treatment with the medication. Atorvastatin has an approximate elimination half-life of 14 hours. [15] In a Cochrane systematic review the dose-related magnitude of atorvastatin on blood lipids was determined. The ortho-hydroxy metabolite undergoes further metabolism via glucuronidation. In addition, they can exert antiatherosclerotic effects independently of their hypolipidemic action. See figures down. Lipitor, the cholesterol-lowering medication, has become the bestselling pharmaceutical in history.
